P0465: Purge Flow Sensor Circuit Malfunction
Can you still drive? Yes, this code has no impact on driving performance or safety. It only affects EVAP system monitoring.
What Does P0465 Mean?
Code P0465 indicates a malfunction in the EVAP purge flow sensor circuit. Some vehicles use a dedicated sensor to directly measure the flow of fuel vapors being purged from the charcoal canister to the intake manifold. A circuit malfunction means the ECM cannot accurately monitor purge flow, affecting EVAP system diagnostics.

Frequently Asked Questions
Do all vehicles have a purge flow sensor?
No. Many modern vehicles estimate purge flow using other sensors and calculations rather than a dedicated purge flow sensor. This code primarily applies to certain Chrysler, Dodge, and Jeep vehicles.
Can I ignore P0465?
While it will not affect driving performance, it will cause a check engine light and emissions test failure. It should be repaired to pass inspection and ensure the EVAP system is monitored properly.
